... A system consists of a spring attached to a 1.0kg mass that slides on a frictionless horizontal surface. The spring has a force constant of 200N/m. a. If the spring is stretched to a distance of 0.20m from the equilibrium position, what is the potential energy of the system? b. What is the speed of ...

Chapter 7: Energy
... The potential energy of the ball is the same at the top, in all three cases, because the total work done, W = Fd = mgh is the same whether lifted, pushed, or hopped up. (This assumes no force needed to move it horizontally – so neglecting friction) Another important note! h is defined relative to so ...

... OPPOSITE direction, yet still on the same axis, you get a NEGATIVE WORK VALUE. This negative doesn't mean the direction!!!! IT simply means that the force and displacement oppose each other. The ANGLE between the force and displacement in this case is 180 degrees. What happens when you put this in f ...
